Black-rumped Magpie
The black-rumped magpie (''Pica bottanensis'') is a species of magpie found in central Bhutan to west-central China. It was formerly classified as a subspecies of the Eurasian magpie (''Pica pica''). A molecular phylogenetic study published in 2018 found that the black-rumped magpie is a sister taxon In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree.

Adolphe Delessert
Adolphe François Delessert (15 September 1809 – 6 April 1869) was a French explorer and naturalist. A nephew of Baron Jules Paul Benjamin Delessert, Benjamin Delessert, he accompanied George Samuel Perrottet, Perrottet on a journey to India and Southeast Asia. During the course of five years that began on 24 April 1834, he collected several new species of plants and animals including the Wayanad laughingthrush which he collected on the slopes of the Nilgiris and was named by Thomas C. Jerdon as ''Garrulax delesserti'' in his honour. He travelled through Mauritius, Reunion Island, Penang, Pondicherry, Malay Peninsula, Singapore, Java, and Madras returning on 30 April 1839. He used German botanical artist Jean-Christophe Heyland (1791-1866), for some of the illustrations in his books. In 1843 he published a book ''Souvenirs d'un Voyage dans l'Inde exécuté de 1834 à 1839'' about his travels and included illustrations including landscapes by V. Dollet and animals by JG Prêtre ...

Bumthang Valley
Bumthang Valley is the main inhabited valley in the Bumthang district of Bhutan. History Bumthang is one of the most beautiful and sacred valleys in Bhutan. The main town in the valley is Jakar. Bhutan's only brewery, brewing Red Panda wheat beer, is in Jakar. Bumthang is divided into four '' gewogs'', namely Chhoekhor, Tang Tang or TANG most often refers to: * Tang dynasty * Tang (drink mix) Tang or TANG may also refer to: Chinese states and dynasties * Jin (Chinese state) (11th century – 376 BC), a state during the Spring and Autumn period, called Tang (唐) b ..., Chhume and Ura. The valley is broad with various habitats including coniferous woodland. The language spoken in Bumthang is known as Bumthangkha, a Tibeto-Burman language. Each of the four valleys of Bumthang has its own dialect. References Valleys of Bhutan {{Bhutan-geo-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bhutan
Bhutan (; dz, འབྲུག་ཡུལ་, Druk Yul ), officially the Kingdom of Bhutan,), is a landlocked country in South Asia. It is situated in the Eastern Himalayas, between China in the north and India in the south. A mountainous country, Bhutan is known as "Druk Yul," or "Land of the Thunder Dragon". Nepal and Bangladesh are located near Bhutan but do not share a land border. The country has a population of over 727,145 and territory of and ranks 133rd in terms of land area and 160th in population. Bhutan is a Constitutional Democratic Monarchy with King as head of state and Prime Minister as head of government. Mahayana and Vajrayana Buddhism is the state religion and the Je Khenpo is the head of state religion. The subalpine Himalayan mountains in the north rise from the country's lush subtropical plains in the south. In the Bhutanese Himalayas, there are peaks higher than above sea level.

Magpie
Magpies are birds of the Corvidae family. Like other members of their family, they are widely considered to be intelligent creatures. The Eurasian magpie, for instance, is thought to rank among the world's most intelligent creatures, and is one of the few non-mammal species able to recognize itself in a mirror test. They are particularly well known for their songs and were once popular as cagebirds. In addition to other members of the genus '' Pica'', corvids considered as magpies are in the genera '' Cissa'', ''Urocissa'', and ''Cyanopica''. Magpies of the genus ''Pica'' are generally found in temperate regions of Europe, Asia, and western North America, with populations also present in Tibet and high-elevation areas of Kashmir. Magpies of the genus ''Cyanopica'' are found in East Asia and the Iberian Peninsula. The birds called magpies in Australia are, however, not related to the magpies in the rest of the world. Name References dating back to Old English call the bird a "p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Eurasian Magpie
The Eurasian magpie or common magpie (''Pica pica'') is a resident breeding bird throughout the northern part of the Eurasian continent. It is one of several birds in the crow family (corvids) designated magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "magpie" is used by English speakers as a synonym for the Eurasian magpie: the only other magpie in Europe is the Iberian magpie (''Cyanopica cooki''), which is limited to the Iberian Peninsula. The Eurasian magpie is one of the most intelligent birds, and it is believed to be one of the most intelligent of all non-human animals. The expansion of its nidopallium is approximately the same in its relative size as the brain of chimpanzees, gorillas, orangutans and humans. It is the only bird known to pass the mirror test, along with very few other non-avian species. Taxonomy and systematics The magpie was described and illustrated by Swiss naturalist Conrad Gessner in his '' Historiae animalium'' ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Sister Taxon
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomi ...

Asir Magpie
The Asir magpie (''Pica asirensis''), also known as the Arabian magpie, is a highly endangered species of magpie endemic to Saudi Arabia. It is only found in the country's southwestern highlands, in the Asir Region. It occurs only in African juniper forest in well-vegetated wadis and valleys. It was formerly classified as a subspecies of the Eurasian magpie (''Pica pica''), and still is by many authorities. This species is highly threatened by habitat destruction, as its native forests are not regenerating. Tourism development and climate change are also posing a threat. Only 135 pairs (270 mature individuals) are known to survive in the wild, and this number is declining. A molecular phylogenetic study published in 2018 found that the Asir magpie was a sister taxon to the black-rumped magpie that is found on the Tibetan Plateau. Description The Asir magpie (''Pica asirensis'') is about 45-60 cm long, and its approximate weight is 240 g. Its head, neck, back, front c ...

Pica (genus)
''Pica'' is the genus of seven species of birds in the family Corvidae in both the New World and the Old. They have long tails and have predominantly black and white markings. One species ranges widely from Europe through Asia, one occurs in western North America, one is restricted to California, one is restricted to southwestern Saudi Arabia, and one occurs across North Africa; the last two are often considered subspecies of the Eurasian. They were previously considered closely related to the blue and green magpies of Asia, but recent research suggests their closest relatives are instead the Eurasian crows. Taxonomy The genus ''Pica'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. He derived the name by tautonymy from the specific epithet of the Eurasian magpie ''Corvus pica'' introduced by Linnaeus in 1758. ''Pica'' is the Latin word for the Eurasian magpie. A molecular phylogenetic study published in 2018 found that the Eurasian magpie consisted of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1840
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...
